We have OOPS, or Object-Oriented Programming System, in programming languages, which is a programming paradigm supported by multiple languages in which we build our system in terms of real-world items utilizing classes and objects. you must be clear with the concept of these two terms. Abstraction is a technique for hiding complexity and providing a simple user interface. So the variables can be accessed only through the public methods outside the class since private objects are not accessible outside class but accessible inside class. Hierarchical classification allows you to deal with a complex abstraction. In other words, the user will have the information on what the object does instead of how it does it. The end user will have no idea about the implementation specifics once the icon on the GUI is clicked. For example, you dont need to know how your camera recognizes a human face in an image or how it calculates gamma correction. Encapsulation: Binding (or wrapping) code and data together into a single unit is known as encapsulation. 2) Encapsulation is also called data hiding.
